I think the left/right/liberal/centrist distinction is a lot less useful at this point than the "wants to be an adult member of society" vs "fuck you mom" divide.
Take: the Leo Frank stuff is a much worse acceleration of left-wing people on Twitter deciding that the word “r-tard” was an acceptable statement to call someone again. There’s a bizarre belief that acting like a neo-Nazi or an alt-righter is liberating in some way way.
